heh i just mastered 2 pitches getting rid of my 2-seam and my slider and replacing it with a splitter and a 12-6 curve which is my strikeout pitch 
 
my windup is like josh beckett after i went a month trying to find a perfect delivery and arm angle 
 
4-seam 81-87 (if i release it wrong it will break like a slider which was weird to me but cool) 
changeup 73-75 finally learned how to control it 
12-6 curve 61-65 nasty break 
splitter 75-79 my newest pitch that just drops after i throw two fastballs
